Cultural Values as Contributors to Latinx Student Grades

open access: yesInternational Journal on Studies in Education, 2023
Cultural discontinuity, or the misalignment of learning processes based on cultural values practiced at home and at school, is one factor that has been explored in the educational experiences of racial/ethnic minority students. The purpose of the current

A Versatile Microfluidic Extrusion‐Based Hydrogel Platform for Self‐Organization and Long‐Term Maintenance of Engineered 3D Lymphatic Endothelium

open access: yesAdvanced Healthcare Materials, EarlyView.
Microfluidic coaxial extrusion generates size‐controlled 3D lymphatic tubes from primary human dermal lymphatic endothelial cells in a defined four‐component matrix. These engineered vessels self‐organize into stable lymphatic endothelium, maintain selective macromolecular permeability for 30 days, and enable direct comparison with blood endothelial ...

How Reclamation Policy Shapes China’s Coastal Wetland Ecosystem Services

open access: yesSystems
China’s reclamation regulation policy is an important policy tool used by the government to balance land development and ecological protection in coastal areas, but few studies have focused on the impact of the implementation of this policy on ecosystem ...

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

open access: yesAdvanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Direct Synthesis of High‐Valence Protein@UiO‐66 Composites: Linking Crystallization Pathways to Protein Encapsulation

open access: yesAdvanced Materials, EarlyView.
This work reports a direct, biocompatible method to synthesize UiO‐66, enabling one‐step encapsulation of proteins without compromising crystallinity or activity. Using advanced in situ and ex situ techniques, the study reveals that proteins integrate concurrently with MOF growth, forming crystalline protein@UiO‐66 nanoparticles, and provide insight ...

Regression Discontinuity Designs With a Continuous Treatment [PDF]

open access: yesJournal of the American Statistical Association, 2018
The standard regression discontinuity (RD) design deals with a binary treatment. Many empirical applications of RD designs involve continuous treatments. This paper establishes identification and robust bias-corrected inference for such RD design.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

open access: yesAdvanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Programmable 3D Photovoltaics via Mechanically Origami‐Coded Interlocked 3D Kirigami and Nano‐Root Anchored AgNWs–In–Ga Multiphasic Alloy Conductor

open access: yesAdvanced Materials, EarlyView.
Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

Evidence on the deleterious impact of sustained use of polynomial regression on causal inference

open access: yesResearch & Politics, 2015
It is common in regression discontinuity analysis to control for third- or fifth-degree polynomials of the assignment variable. Such models can overfit, leading to causal inferences that are substantively implausible and that arbitrarily attribute ...
